What are some movies where two awkward or even average people fall in love?

So many movies are about how "the geek gets the girl" (or guy). I enjoy them are fantasy fluff - but it's also nice to see that people don't need to catch the stereotypical hot person to be a story worth showing.

What are some movies you like where people in the same so-called " league" (I'm not hashing out leagues here, just using it as a description) fall for each other?
